PAUL w. YBEAUCI-IAMP AND enoa'en BECKAM, or OAKLAND, OALIFORNTA, SSIGNQB or ONE-FOURTH, 'ro HARRY c. scnnonnim or OAKLAND, CALIFORNIA REP-EATING RUBBER BAND RIFLE" 1 Application filed; August 27, 19:32 semi no. 630,668.

This invention is a repeating rubber band rifle, and is specially directed to a rifle which I trol means providing for extremely rapid vsuccessivefire of the bands or for shooting the bands successively one at a time.

A further object of the invention is to pro vide sights for the rifle which sights will be zo automatically adjusted for-the shooting of the various bands, whereby the sights will always be correct irrespective of the angular relation of the band being shot or pro]ected.

Other objects and advantages of ther in- 7 vention will becomeapparent as the followv ing description is read on the drawing forming a part of this specification, and in which similar reference characters are used to designate similar parts throughout the several views, of which:

's a side elevation of myinvention, loaded with a plurality of rubber bands.

Fig. 2 is a side elevation of the invention 2, 4 and 5, the front sight consisting'xof a groove 25 which is formed in'thetop 'sur-' 7 face of the muzzle. The rear sightconsists p artly shown in section to show the operating or release mechanism for the rubber bands.

Fig. 3 is an enlarged fragmentary view of the hand holding and band releasing means.

Fig.4 is a section taken on line 41-41: of Fig. 3.. 1

Fig. 5 is a Fig. 6 is a view similar to Fig, 3., showing the releasing mechanism in position for. releasing one of the bands.

section taken on line of The invention consists of a barrel 10,.the

muzzle of which is provided withla concavity 11 adapted to retain the rubber bands 12 in poslt on, the-barrel terminating at its rearward end n a breech 18;which is provided on its upper surface with a plurality of pro-1,-

jections or lugs 14, which may be formedin the material, or may be'formed by means of pins, over which the rearward ends of the rubber bands 12 are to be secured as is clearly indlcated in Fig. 1, the stock 15 being in-j tegral with the breech and being formed in the conventional manner.

lhe breech 13 is provided with a slot 16in which the release 17 1S-':Slldl.bly mountedfor reciprocal movementithroughout the length of the teeth 14, and the exterior of the two walls of the breech are each provided with a groove 18, these groovesextending throughout the length of the breech.

The release mechamsmconsists of a platelike member 17 having a circular recess 19 formed in the upper end, in which is rotatably mounted a disc 20, the disc QObein-g inserted sidewise into the recess andretained by the upwardly extending edges 21, which" projectbeyond the horizontal center oflthe disc. Secured to the lower end ofthe release plate 17 are oppositely disposed guides '22,

,. which are each provided with atongue 23 which is slidable in the groove 18,:the combination of the members 17 and 22 forming together, the'itrigger 2 L (Sights are provided as indicated, ill-Figs.

of an annular groove 26 formed inthe disc "20, this groove extending entirely about the periphery of the disc whereby the sight is provided irrespective of the rotative position? tatable disc permitting the bands to be raised sufficiently high to clear the teeth, and offering no restraint to the band when released. The trigger 24 may be drawn back suflicient to release only one band at a time if desired, orif drawn back quickly its full distance of travel, the entire number of bands Will be quickly and successively released, but in no case is it possible to obtain simultaneous're lease of two bands as is readily apparent.

The sights automatically take care of the" location of the band on the teeth 14 as it will be noted that a band passing over the muzzle and extending over the first tooth will be de- I flected downwardly when releasedmore than another band which extends over the last tooth, and that the deflection will be dependent on the top of the disc 20 relative to the muzzle 11 andas the sight is formed in the disc 20, the disc'deflection is compensated for "by the positioning of the sight always at the point of releasing of the band.

Having described an operative device it will be understood that variations in construction and arrangement of parts which are consistent with the appended claims may be j resorted to without detracting from the spirit or scope of the invention or sacrificing any I of the advantages thereof.

7 We claim:

1. Releasing means for a rubber band rifle v comprising a slidingmember and a disk rotatable therein, said vdisk peripherally cooperating-successively with tensioned rubber bands to release the bands.

2. Releasing means for rubber bands and a rear sight for a rubber band rifle comprising a sliding member and a disk rotatable therein, said disk peripherally cooperating successively with the tensioned rubber bands to release the. bands, said disk having a peripherally formed annular groove to form the rear sight for the rifle.

3. In combination with a rubber band rifle,

releasing means for the tensioned rubber bands comprislng a trigger slidable in the breech of the. rifle and having a circular re- "cess formed in the upper portion of the trig- .g'er and a disk rotatable in the recess-and ex- 4. In combination With a rubber band rifle,

"releasing means for the tensioned rubber bands comprising a trigger slidable in the breech of the rifle and having a circular recess formed in the upper portion of the trigger and a disk rotatable in the recess and extending above the top of the trigger, said disk cooperating successively with the tensioned rubber bands as the trigger is slid of, a member mounted for reciprocal movement in the slot and a disk rotatable in a circular recessformed in the upper portion of the member, said disk forming a non-resistant cam for releasing the tensioned bands successively. V v v v 6. Releasing means for a rubber bandrifle comprising, in combination with stepped tensioning means for a plurality of rubber bands; an elongated slot formed vertically through the breech and longitudinally thereof, a member mounted for reciprocalmovement in the slot and a disk rotatable in a circular recess formed in the upper portion of the. member, said d1sk forming a non-resistant cam for releasing the tensioned bands successively, and an annular groove peripherally formed in the disk to form an automatically adjusted rear sight for the rifle.

7. Releasing means for tension-ed rubber bands comprising a sliding member, a disk rotatably mounted in the sliding member,the disk forming a cam to release the rubber 1 bands.

8. Releasing means for tensioned rubber bands comprising a sliding member, a disk rotatably mounted in the sliding member,'the disk forming a cam to release the rubber bands, and an annular grooveperipherally formed'in the disk and forming a rear sight.

9. Tensioning and releasing means for a rubber band rifle comprising a breech provided on the upper surface with a series of back-cast teeth, and a cam member slidable in the breech and extending above the top of the teeth, said cam member consisting of a disk rotatablein a circular recess formed i a sliding member; I

10. Tensioning and releasing means'for a rubber band rifle comprising a breech provided on the upper surface with a series of back-cast teeth, anda cam member slidable in the breech and extending above the top of the teeth, said cam member consisting of a disk rotatable in acircular recess formed in a sliding member, said disk forming a rear sight for the rifle bymeans of a peripheral annular groove formed in the disk. 11. A rubber band rifle comprising a barrel having a concavity formed in the muzzle and a front sight consisting of a groove formed in the top adjacent the nozzle, a breech having longitudinally formed therethrough in a vertical plane, an elongated slot, and a series of back-cast teeth formed in the upper surface of the breecln'a releasing member slidable in the slot and having a rotatable rubber-band-releasing cam extending above the top of the teeth, a peripheral groove formed in the cam providing a rear sight and a stock integral with the breech.

In testimony whereof We afiix our signatures.
